The Zang Sun clan of the Lu State came from Lu Xiaogong. Lu Xiaogong's son, Zizi Zang, was called "Zang Aibo" after his death, and Zang's family passed on to Zang Sun Su for five generations. The Zang Sun clan has a noble status, a prosperous family, second only to Sanhuan in power, and is famous for being a good minister and a wise man, but the Zang Sun clan has never held the power of Shangqing.

Zang Sunsu's mother is the niece of Mu Jiang, the Duchess of Lu Xuan (Zang Sunsu wants to call Mu Jiang "aunt"); After Zang Sun Su was born, Mu Jiang especially liked this smart and clever boy, so he kept him by his side and raised him as his own child.

Later, Mu Jiang and his uncle Sun Qiaoru tried to shake the office and get rid of Ji Wenzi and Meng Xizi. But the coup d'état was crushed, his uncle and grandson Qiaoru went into exile in Qi, and Mu Jiang was placed under house arrest until death; Because Zang Sunsu was implicated by the two, he has been treated unfairly by Sanhuan.

However, Zang Sun's skillful use of superhuman wisdom won Ji Wenzi's trust, and later won Ji Wuzi's favor and became Ji Sun's loyal partner.

A few years ago, after many mediations, Meng Xianzi finally persuaded the Duke of Jin to make the state of Yan a vassal state of the state of Lu; In this way, the Lu people passed on part of the burden of their own tribute to the Jin State. At that time, Shangqing Ji Wenzi was already dying, and Meng Xianzi had been secretly competing with his uncle and grandson for the qualification of successor. Meng Xianzi calculated that he had made such a miraculous feat, and he would definitely defeat his opponent and obtain the status of Shangqing.

Just when he was complacent, Ju and Di were secretly instructed by the people of Qi to attack Yan endlessly. As the protectorate of the Yan State, Lu must come to the rescue.

The task of rescuing Yan was supposed to be carried out by Meng Xizi, but Ji Wenzi felt that Meng Xizi was in the limelight enough, and his heart was biased, so he handed over this "beautiful difference" that could make contributions to Zang Sunsu. However, Zang Sun Su did not have a meritorious life, but the army under his command was almost completely annihilated by the division at the Fox Pass (in the fourth year of Lu Xianggong). After Meng Xianzi received the news, a nameless fire instantly arched in his heart, he spit out a mouthful of old blood, and almost died on the spot.

Later, Ju continued to attack Yan, but Lu was powerless to rescue and could only watch the protected perish. This outcome not only made all of Meng Xianzi's efforts in vain, but also caused him to be complained and strongly questioned by the countrymen, and at the same time greatly elevated the status of his uncle and grandson Bao (because he had always opposed the inclusion of the state of Yan as a protector, and his prophecy was fully fulfilled).

After Ji Wenzi's death (in the fifth year of Lu Xianggong), his uncle and grandson Leopard were promoted to Shangqing without any suspense. The Mengsun clan formed a deep enmity with the Zang Sun clan, and in order to protect himself, Zang Sunsu got closer to Ji Wuzi.

Ji Wuzi's wife has no son. According to the Zhou rites, he should pass the throne to the eldest concubine Gongmi, but he pampered his second son Ji Sun Su (Ji Mourning Zi) and wanted to make him his son-in-law.

Ji Wuzi asked the elder Shen Feng for help: "Mi and Su are both my favorite sons, but I want to be a talented son, what should I do?" ”

Shen Feng didn't want to get involved in the Ji family's succession dispute: if he chose the right position and wealth, he would not increase a single point, and the wrong choice would likely lead to the evil consequences of no bones. He also knows the little routine of Ji Wuzi's speech - Ji Wuzi is not asking him for advice at all, but wants to use his words to strengthen his inner confirmation. Therefore, as if he hadn't heard anything, Shen Feng arched his hand and quickly retreated. When he returned home, he told his family, "Pack your bags and be ready to go." ”

A few days later, Ji Wuzi asked him the same question again, and Shen Feng said, "Master asks this question, and I am going to leave Master!" ”

Ji Wuzi didn't want to force this loyal and honest retainer away, so he had to turn to Zang Sun Su for a solution. Zang Sunsu is not without the same worries as Shen Feng. But he did not dare to refuse the request of the backer, and he was too confident in his cleverness, so he said: "I can solve the troubles for the master, and the master will find an opportunity to invite me and the doctors to have a drink, and I can leave the rest to me." ”

A few days later, Ji Wuzi hosted a banquet for a number of public doctors and celebrities, Zang Sun Suzhi sat proudly on the guest of honor, and the other guests also sat down. After the banquet began, Ji Wuzi first toasted to Zang Sunfu, and Zang Sunsu drank it all with his neck up; He put down the wine and suddenly asked, "Master, there is one less guest!" ”

Ji Wuzi didn't know anything about Zang Sun Su's plan, and asked suspiciously: "The guests have already arrived, otherwise they can't have a banquet!" ”

With an unpredictable smile on his face, Zang asked the servants to add an additional seat to the north (the main seat) and spread two layers of seats (the Zhou rites stipulated that the princes should have three seats, two for the princes, and one for the scholars). After the seat was settled, Zang Sun Su said, "Master, please summon you!" ”

The chief director of this drama is Zang Sunsu, although Ji Wuzi has doubts, he doesn't dare to ask more, so he can only summon Ji Sunsu at his request.

After Ji Sunsu came in, Zang Sunsu walked down the steps quickly; The guests did not dare to slack off, and stood up with the guest of honor. Zang Sunsu smiled and put the confused Ji Sunsu in the right position. Ji Sunsu looked very nervous, his expression was extremely unnatural, he seemed hesitant with every step he took, and the hand holding the cup kept shaking after sitting down.

Ji Wuzi still didn't understand Zang Sunfu's intentions, and later he began to toast the guests in turn according to the procedure, and after the host finished toasting, the guests returned to the host; The host then asked the vice-host (equivalent to the vice-attendant) to toast.

The last link was the mutual respect of the guests, and Zang Sun Su stopped again. He also asked Ji Wuzi to place a place among the non-commissioned guests.

Then ** appeared, and the mystery was revealed.

Zang Sun Su asked Ji Wuzi to summon Gongmi and let Gongmi sit in that position. When Gongmi entered the door and saw his younger brother sitting on the upper seat, he couldn't help but be furious, but he immediately suppressed his anger and obediently walked to his place. The doctors looked at each other; Ji Wuzi was stunned; Zang Sun Su was complacent.

Zang Sunsu used this roundabout and tactful method to solve the problem of Ji's succession.

Ji Wuzi then appointed Gongmi as the family Ma Zheng (equivalent to the Sima of the Ji Army, in charge of military affairs), which was regarded as a consolation prize for him. But Gongmi hid in his room and sulked, and he did not go out for several days, neither thanking his father nor taking office.

His friend Min Zima (Min Ma's father) went to visit him and said, "You must not fight against your father!" There is no way for good or evil, only people are called. As a son, he should only worry about whether he can fulfill his filial piety, and not care about how much benefit he can get. Respectfully carry out your father's orders, are you still afraid that heaven will not be able to bless you? If you can honor your master, you can even be richer than Ji's. If you try to do something unlawful, you will bring more trouble than the lesser people. ”
